I am not really a fan of this for similiar reasons.

But also because I believe all this does is making people either build full Physical tanks or full magical tanks. (cause lets be honest 40/40 both is already feeling like you are made of paper unless you have other reductions, halving one makes you just not build it at all and focus on the other.)

What that means is that you technically reduce the stat spread and open a weird situation where people are tanky but not really simply because of the sheer amount of access from both Physical and Magical damage types in almost every class.
And because of a thinner stat spread its like they become even more DPS Tanks...With one weakness. I think thats a weird way of balancing the game. I think it just kills Tanks, while tanking isn't even the issue.
